A trio of Tulsa teenagers have been charged with one count each of felony murder and one count each of attempted armed robbery following a botched stickup that left a truck driver dead.

Jermaine Savory, Damian Anderson, and Frankie Jackson, Jr., all 17, were arraigned Tuesday afternoon in Tulsa County District Court. All three entered not guilty pleas.

The three teens are charged with the shooting death of 53-year-old Robert Horton, of Arlington, TX.

Horton was shot and killed at around 6 a.m. on Saturday, March 23 as he and his driving partner were delivering food products to a Papa John’s pizza franchise at 2802 E. 11th St.

Horton was shot outside the business as he was unloading some of the freight, while his driving partner remained in the trailer. It was previously reported that Horton’s partner was inside the store when the shooting occurred.

The suspects are alleged to have waited outside in an SUV, parked nearby behind a wooden fence. At least two suspects got out and lost Horton temporarily when he went into the building. They drove off but came back when they saw Horton come outside.

At least two suspects got out of the vehicle and approached Horton while he was an estimated 30 feet from the trailer, on the other side of the building.

A stolen handgun is believed to be the murder weapon. Tulsa police were still searching for the gun late last week.

Felony murder occurs when someone is killed during the commission of a felony, such as robbery. If convicted of the charges, the suspects face a maximum penalty of life without parole.
